Answer:
-17x² + 3x
Step-by-step explanation:
(-8x² + 3) + (-9x² + 3x - 3)
-8x² + 3 - 9x² + 3x - 3
-17x² + 3x
-2 = -2 because of the slope
If y varies inversely with x, then we know that:
y = k/x
We are given x and y, so plug in the numbers and solve for k.
1.5 = k/6.4
k = 1.5*6.4
k = 9.6
Answer:
P (arts) = 0.25
P (psychology) = 0.25
P (geology) = 0.5
Step-by-step explanation:
Let the probability of choosing art = x
As given that she is equally likely to choose art or psychology and twice as likely to choose geology.
So,
P (arts) = x = P (psychology)
P (geology) = 2x
The sum of the probability = 1
So,
P (arts) + (psychology) + P (geology) = 1
x + x + 2x = 1
<u>x = 0.25</u>
<u>P (arts) = x = 0.25</u>
<u>P (psychology) = x = 0.25</u>
<u>P (geology) = 2x = 2*0.25 = 0.5</u>
Y > -3x/4 - 1 (this is the answer)
